I found this idea on another blog, however, I don't remember exactly which one it was. Basically, I loved the idea because T is a snack grazer. She is constantly eating through out the day. I decided to use a muffin tin of assorted, healthy snack foods. At the time, I only had a muffin tin for 12 but now, I use one for 6.
It works great! T doesn't complain about any of the foods, because even if she doesn't want one thing, she usually has something else that she does want. And, I get to choose the snacks this way.
